Description RamaKasturi 2015-04-28 04:47:42 UTC

Description of problem:
As of now when rebalance / remove-brick is running user is allowed to take snapshot, snapshot creation succeeds but does not display any snaps.

user should be given a message saying "Rebalance/remove-brick is running for the volume <vol_name> and snapshot cannot be taken. 

Version-Release number of selected component (if applicable):
ovirt-engine-3.6.0-0.0.master.20150420232310.gite30f655.el6.noarch

How reproducible:
Always.

Steps to Reproduce:
1. Create a volume and start running rebalance on the volume.
2. Now click on the snapshot and say 'New'
3. New dialog loads and provide the snap name.

Actual results:
Snapshot creation succeds with no snapshots and event message is displayed saying "Snapshot <snapname> created for volume <vol_name>"

Expected results:
user should not be allowed to take snapshots when rebalance / remove-brick is running.

Comment 2 RamaKasturi 2015-05-21 05:11:27 UTC

Moving this bug back because the error message mapping is not proper.

When rebalance or remove brick is in progress UI displays the following error message "Error while executing action: Cannot create ${type}. A task is in progress on the volume ${volumeName} in cluster ${vdsGroup}

Instead of task is in progress, can we display the actual task which is in progress?

ovirt-3.6.0-3 release

Comment 4 RamaKasturi 2016-02-02 09:24:52 UTC

Tested with RHEV 3.6.2.6 and RHGS Nightly ( glusterfs-3.7.5-17.el7rhgs )

Snapshot creation during rebalance fails with the error "Error while executing action : Cannot create Gluster Volume snapshot. A rebalance operation is in progress on the volume <vol_name> in cluster <cluster Name>

Snapshot creation during remove-brick fails with error " Error wile executing action: Cannot create Gluster Volume Snapshot. A remove_brick operation is in progress on the volume <vol_name> in cluster <cluster Name>
